Give Gov. Chris Christie some credit. He’s willing to work for his support.

The governor, during an appearance on the Philadelphia sports radio station WIP Monday, ran across a New Jersey caller angry that Christie had abandoned his hometown choices for football for the hated Dallas Cowboys.

Christie explained he became a Cowboys fan in the 1970s when Hall-of-Fame quarterback Roger Staubach was running the team.

There was a bit of the front-runner mentality with Christie’s choice. His father, Bill, is a New York Giants fan, and in the 1970s, the Giants were a terrible team.

“The only person I was a bigger fan of than the (Philadelphia) Eagles was Chris Christie until his affiliation with the Cowboys,” said John from Hammonton. “You have lost my support for the governor and, if you run for president, for president.”

Calling Christie’s reasoning for becoming a Cowboys fan weak, John then ramped up his criticism.

“We can’t have somebody running the country like that,” he said.

“Oh, really,” Christie said.

“Yes!” said John.

“Come on, Roger Staubach,” Christie replied.

John then implied that Christie was merely a front-runner, interested in whoever could win.

“This is weak,” John told Christie. “I thought you were strong.”

John had a solution, though. If, during Christie’s next visit to Hammonton, the governor would stop and have dinner with the caller, he would reconsider his support.

“I want to be one of the guys who doesn’t have to pay $10,000 to come and get a picture with you, shake your hand and meet you,” John offered.

“The next time I’m in Hammonton, I will do that,” Christie said. “The next time I’m in Hammonton, my staff is going to call you and we’re going to get together.”

“I love it,” John replied.

Christie’s WIP appearance was part of a South Jersey swing today that includes numerous stops in Camden. South Jersey is foreign sports territory for the North Jersey-born Christie, but his wife, Mary Pat, is from Pennsylvania and is an Eagles and Phillies fan.
